Hi Pavel,

When you say the music plays do you mean to say it plays through HDMI or
does it play through the speakers?

$ aplay -l / $ pasuspender -- aplay -l

I have an Intel laptop with integrated ALC233 for example. Im my dmesg I
see the following log:

[19.955428] snd_hda_codec_realtek hdaudioC0D0: speaker_outs=0
(0x0/0x0/0x0/0x0/0x0)

I believe you should see something similar. Please check dmesg of both good
working kernel and bad non-working kernel.

Thanks,
Geraldo Nascimento
